# Supply and Demand: End of Chapter Problems

**9. Adjust each graph to show the indicated change. In each graph, click on the line or its midpoint to see the options.**

## a. An increase in quantity demanded

**Description:** 
- The graph shows a downward-sloping demand curve labeled "D." 
- The initial demand curve is shown in black.
- An increase in quantity demanded is represented by a movement along the curve to a lower point, which may reflect a lower price.

## b. A decrease in demand

**Description:**
- The graph portrays a similar downward-sloping demand curve labeled "D."
- The original demand curve is shown in black.
- A decrease in demand is illustrated by a parallel shift of the entire curve to the left, indicating that less quantity is demanded at every price level.

**General Explanation:**
- **Price** is represented on the vertical axes of both graphs.
- **Quantity** is represented on the horizontal axes.
- These visualizations aim to help understand changes in demand and the graphical representation of these changes.

The image contains two graphs illustrating supply concepts.

**Graph a: An Increase in Supply**
- The graph shows two supply curves, labeled as initial and new.
- The initial supply curve is shifted to the right, indicating an increase in supply.
- The vertical axis represents price, and the horizontal axis represents quantity.
- An increase in supply typically means that more quantity is available at the same price.

**Graph b: A Decrease in Quantity Supplied**
- The graph displays a single supply curve with a movement along the curve.
- The point starts high on the curve and moves downward.
- The vertical axis represents price, and the horizontal axis represents quantity.
- A decrease in quantity supplied reflects a reduction in the amount available at a given price, without a shift in the overall supply curve.
